SPECIFICATION forming part of Letters Patent No. 658,847, dated October 2, 1900.

' Application tied February 16, 1900. serial No. 5,498. No model.)

To a/ZZ whom itmtty concern: l

Beit known that I, GEORGE R. HILL, a subject of the Queen of Great Britain, residing at St. Louis; in the State of Missouri, have invented certain new and useful Improvements in Automatic Sash-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying draw-r ings, forming a part hereof.

My invent-ion has relation to improvements in automatic sash-locks; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a middle ver-r tical section taken through the window-frame,

showing myldevice in end elevation, the sashbeing up or closed. Fig. 2 is an elevation of the sash and my device viewed from the inside of the car, the wall of the box or compartment located below the sill being removed. Fig. 3 isaview similar to Fig; 1, but with the sash lowered into the box. Fig. .4 is a view similar to Fig. 2, but with the sash lowered into the box or compartment below the sill. Fig. 5 is a perspective of the weight and sash-supporting platform carried by it. Fig. 6 is a top plan View of the pocket over which the platform -is mounted. Fig. 7 is a perspective view of the weight or bar carrying the locking-latch; and Fig. 8 is a'section on line 8 8 of Fig. 4, butv with the wall'carr'ying the push-button in place. Y

One object of myinvention is to construe a mechanism which will automatically close and lock a car-window sash n pon the mere depression of a push-button, which releases thelatch by which the sash is held to its open position.

A further object is 'to simplify the mechanism by which the sash is actuated.

In detail the invention may be described as follows:

Referring to the drawings, 1 represents a prevailing type of window-frame, 2 the inner sill thereof, and 3 the outer supporting-ledge for the sash in its closed position. 4 represents the boX or compartment below the sill 2, and 5 the passage-way formed for the reception of the sash in its descent into the compartment 4. Located within the boX 4 between the sill 2 and the bottom of said box i and disposed adjacentto the sash-guide strips 6 are vertical rods 7, and located 4eXteriorly to the rods 7 and spaced farther apart are similar rods 8. Mounted between the planes of each pair of rods in a bracket9 is a grooved pulley 10, over which passes a cord or wire 11; one end of which is secured to a lweight or bar 12,

having terminal loops or tubular enlargements 12', and the other end to a weight or bar 13, having similar terminal tubular enlargements 13. The bar 12 12/ is adapted to travel up and down the rods 7, the tubular ends being passed over the rods and over suitable antifriction-sleeves 14, interposed between the ends 12 and rods 7, the sleeves having their ends burred or expanded to retain them in proper position within the tubular ends 12'.' The bar 13 13 is likewise adapted to travel up and down the rods 8, a similar set of antifriction-sleeves 14 being inserted between the rods and the tubular ends 13 of said bar. The bar 13 has a recess 15 cut along one edge thereof and a suitable spring arm or latch 15/ secured in the line of said recess, the latch being adapted to engage a keeper 16 on the under side of the sill 2 when the baris in its elevated position. The latch can be disengaged from its locked position by a spring-controlled push-burton 17, mounted in the top of the inner vertical wall of the box'4.

Forming a part of the bar 12 is a verticallyprojecting arm or bracket 18, provided with an outwardly-projecting pocket 1.9,the lateral walls of the pocket serving to support a pin 20, to the outer projecting ends of which are pivotally secured the lugs 2l of a tiltingsashsupporting platform 22, which normally rests upon the upper end of the bracket 18. Coiled about the pin 2O within the pocket 19 are the arms of the looped-wire spring 23, the ends of the arms bearing against the outer wall of the pocket, the loop underthe circumstances having a tendency to tilt the platform 22 to an open position. (See Fig. 5.) The platform closes to a horizontal position under the weight of the sash while the latteris in the boX 4, (see Figs. 3 and 4,) the sides of theloop being received in depressions 24,formed along the upper edge of the bracket 18, to allow the platform to assume a perfectly-horizontal position.

The operation of the device is as follows:

IOO

'lhe bar 13 13' more than balances the combined weights of the bar l2 l2', platform 22, and sash S, suspended from the cord ll. If the base of the sash is pulled outwardly, so as to rest upon the platform, (see Fig. 1,) and then forced downward, so as to depress the platform to the bottom of the box 4, the bar 13 13' will be raised, (see Fig. 3,) the latch l5 engaging the keeper 16 and allowing the windowsash to remain at the bottom of the box 4. When the latch is disengaged by the push-button, (see dotted position, Fig. 8,) the weighted bar 13 13 will drop down along the rods 8 8, raising the window back to its original position. lVhen the base of the sash is opposite the u pper surface of the ledge 3,by which time the platform 22 emerges from the boX 4, the spring-loop 23by its resiliency tilts the platform 22 t-o an inclined position', the base of the sash being thus forced outwardly upon the ledge 3, designed for its permanent reception. (See dotted position, Fig. l.)

It is understood that I do not limit myself to the precise details here shown, as the same may be departed from without affecting the spirit of luy-invention.

Having described my invention, what I claim is- 1. In a sash-lock,a suitable sash-supporting platform occupying a position adjacent to the lower edge of the sash for the raised position of the latter, the sash and platform being adapted to be lowered and the parts locked in their depressed position, and to automatically resume their original position upon the parts being released from the locking device, substantially as set forth.

2. In asash-lock, asuitabletilting platform for the support of the sash, means for lowering and raising the said platform, and retaining the same in either of its extreme positions, and devices for tilting the platform when in one of its extreme positions for throwing the sash off from the supporting-surface of said platform, substantially as set forth.

3. In a sash-lock, a suitable platform for the support of the sash, a weight or bar to which said platform is secured, rods for guiding the bar in its vertical movements, a second weight or bar, guide-rods for the same, a pulley, a cord passing over the pulley and having its ends secured to the respective weights aforesaid, a locking device for said second weight or bar, and means for disengaging the locking device, substantially as set forth.

4. In a sash-lock, a suitable platform, lugs for the same, a bracket, a poc'ket for said bracket,a pivotal pi n passing through the lugs and through the lateral walls of the pocket, a loop havingarms coiled aboutthe pin within the pocket, the loop normally bearing against the under surface of the platform and tending to tilt the same, depressions formed in the bracket for receiving the sides of the loop to insure a true horizontal position for the platform when supporting,r the sash, means for raising and lowering the platform, a supporting-ledge for the sash, the platform being adapted to throw the sash laterally upon the ledge when the lower edge of the sash comes opposite said ledge, substantially as set forth.

5. A sash-lock comprising a platform for the sash, a compartment for receiving the sash located below the window-sill, a. weight having tubular enlargements carrying said platform, antifriction-sleeves within the enlargements,guiderods over which said sleeves pass, located below the sill, a second weight or bar having tubular enlargemeu ts and similar sleeves and guide-rods therefor, a pulley mounted below t-he sill, and having a cord passing over the same with its ends secured to the respective weights, a recess formed in the second weighted bar, a latch located in the path of such recess, a keeper in the sill for engaging thelatch, a push-button carried by the inner wall of the compartment below the sill, and operating through said recess and adapted to engage the latch, the parts operating substantially as and for the purpose set forth.

6. In a sash-lock, a suitable window-frame having the usual inner sill and outer supporting ledge for the sash, means for depressing the sash below sill and ledge and locking the parts in said position, and devices for disengagiug the parts from their locked position, and raising the sash and depositing the same automatically upon the ledge, substantially as set forth.

7. In a sash-lock, a suitable window-frame, having the usual inner sill and outersash-su pporting ledge, means for permitting the depression of the sash below the sill and ledge, and mechanical devices for automatically returning the sash to its original position, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
